Description
Technical field
The present invention relates to the components of bar straightener technical field, concretely relate to bar straightener cutting blade assembly.
Background technique
Bar straightener cutting blade assembly, including reinforced bar cutter knife, tool apron and hydraulic cylinder, the hydraulic cylinder have hydraulic cylinder
Body and piston rod are mounted on tool apron before the hydraulic cylinder, and the reinforced bar cutter knife is connected to piston rod, hydraulic cylinder
It upholds, piston rod moves forwards, and drives reinforced bar cutter knife to move forwards, can cut off to reinforcing bar；In order to make piston rod can
To move forwards automatically, a return spring is installed behind piston rod；In the prior art, return spring is inside hydraulic cylinder
, or a cover is set behind hydraulic cylinder, in the cover that return spring is mounted on, since return spring is rapid wear
Part is frequently necessary in use replace or repair, when needing replacing or repair, it is necessary to open hydraulic cylinder or disassembly cover, have
There is the shortcomings that inconvenient maintenance.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned technology, provide a kind of when return spring is needed repairing or replaced
When facilitate bar straightener cutting blade assembly --- the return spring external bar straightener cutting blade assembly of operation.
The technical scheme of the present invention is realized as follows: return spring external bar straightener cutting blade assembly, including steel
Muscle cutoff tool, tool apron and hydraulic cylinder, the hydraulic cylinder have hydraulic cylinder and piston rod, install before the hydraulic cylinder
On tool apron, the reinforced bar cutter knife is connected to piston rod, and hydraulic cylinder is upheld, and piston rod moves forwards, and drives bar cutting
Knife moves forwards, and can cut off to reinforcing bar；It is characterized in that: having rear through-hole, the work behind the hydraulic cylinder
Stopper rod passes through rear through-hole and stretches to be extended below, and what piston rod rearwards extended is extension below, behind extension rear end have
Screw thread installs stop nut on screw thread, and there are also return springs to be mounted on behind hydraulic cylinder between stop nut, described
It is exposed outside return spring.
Further speaking, the stop nut side has locking screw holes, and there are also lock screws to be mounted on locking screw holes
In, lock screw heads on the side of extension below.
Further speaking, washer is provided between the return spring and hydraulic cylinder.
Beneficial effects of the present invention: such bar straightener cutting blade assembly has when return spring is needed repairing or replaced
When the advantages of facilitating operation；
The stop nut side has locking screw holes, and there are also lock screws to be mounted in locking screw holes, lock screw
The side of extension below is headed on, also has the advantages that prevent lock screw loosening effect good；
It is provided with washer between the return spring and hydraulic cylinder, also there is reduction to damage hydraulic cylinder excellent
Point.
Detailed description of the invention
Fig. 1 the structural representation of present invention.
Wherein: 1, reinforced bar cutter knife 2, tool apron 3, hydraulic cylinder 4, hydraulic cylinder 5, piston rod 6, rear through-hole 7, back
Extension 8, screw thread 9, stop nut 10,11 locking screw holes 12 of return spring, lock screw 13, washer.
Specific embodiment
Below with reference to embodiment, the present invention is further illustrated.
As shown in Figure 1, return spring external bar straightener cutting blade assembly, including reinforced bar cutter knife 1, tool apron 2 and liquid
Cylinder pressure 3, the hydraulic cylinder has hydraulic cylinder 4 and piston rod 5, is mounted on tool apron before the hydraulic cylinder, described
Reinforced bar cutter knife be connected to piston rod, hydraulic cylinder is upheld, and piston rod moves forwards, and reinforced bar cutter knife is driven to move forwards, can
To be cut off to reinforcing bar；It is characterized in that: having rear through-hole 6 behind the hydraulic cylinder, the piston rod leads to after passing through
Hole rearwards extends, and what piston rod rearwards extended is extension 7 below, behind extension rear end there is screw thread 8, on screw thread
Stop nut 9 is installed, there are also return springs 10 to be mounted on behind hydraulic cylinder between stop nut, outside the return spring
Face is exposed.
In this way, due to be outside return spring it is exposed, when it is time for repair, just do not have to disassembly cylinder body, directly unload
Stop nut can repair, and the purpose of the present invention may be implemented, simple and fast.
Further speaking, the stop nut side has locking screw holes 11, and there are also lock screws 12 to be mounted on locking
In screw hole, lock screw heads on the side of extension below.
Stop nut can be locked in this way, the F in figure is exactly the direction of lock screw installation.
Further speaking, washer 13 is provided between the return spring and hydraulic cylinder.
It can reduce so hydraulic to the subsequent abrasion of cylinder body.
Above is only a specific embodiment of the present invention, but structure feature of the invention is not limited to this, any ability
Within the field of the present invention, made changes or modifications all cover in the scope of the patents of the invention the technical staff in domain.
